Helmet

A helmet, comprising:

• a protective shell forming an outer surface of the helmet;
• an energy absorbing layer defining an inner surface of the helmet, the protective shell and energy absorbing layer comprising longitudinal ribs that protrude radially inwardly and transverse ribs intersecting the longitudinal ribs at intersections, further comprising front, middle and rear ventilation openings located adjacent at least some of the intersections;
• an integrated subassembly of a shear component and a comfort pad removably mountable to the energy absorbing layer, the integrated subassembly having a base conformable to extend along a front circumferential area of the energy absorbing layer and separated fingers extending from the base that are conformable to extend along at least two of the longitudinal ribs and border at least a first front ventilation opening, wherein
• the shear component comprises a flexible sheet of a sheet thickness with raised ribs extending from the flexible sheet in the base and fingers, wherein the raised ribs have enlarged distal ends;
• and
• the comfort pad comprises a flexible sheet generally coextensive with the shear component and arranged in a stacked configuration with the shear component, the comfort pad having openings for the raised ribs shaped smaller than the enlarged distal ends of the raised ribs, wherein the enlarged distal ends can be forcibly passed through the openings to secure the comfort pad in position relative to the shear component,
• wherein, in response to an oblique impact to the helmet with the integrated subassembly mounted to the energy absorbing layer, the shear component undergoes internal shear to allow displacement between the helmet and the wearer's head.
